Innovative Sound Orientation Game for Visually Impaired Babies and Toddlers

DESCRIPTION

The “Crib” is a groundbreaking orientation game designed specifically for visually impaired (VI) babies and toddlers. This engaging sound-based game encourages movement and exploration by prompting children to navigate towards sound-emitting corners. When a child reaches a corner and presses a button, a new sound cue is activated, fostering crawling and self-orientation. Developed by Goldberg’s students, this toy not only provides a fun and safe play environment but also aids in skill development without requiring constant parental supervision.

  1. The “Crib”…. Christa Wheeler Sirin Yaemsiri Vidya Goli

  2. What are we designing? • Orientation game for visually impaired babies and toddlers • Sound orientation game helps to encourage movement and exploration

  3. Where did the idea come from? • Goldberg’s students designed sound mat • Sound cubes that only sighted children could use • How can we modify toys to benefit blind children?

  4. The Primary Playpen Game • One corner plays a sound • The child must move towards the sound and press a large button signifying that they have reached the corner • Once that button is pressed, another corner, selected at random, begins to play music

  5. What does this toy do? • Encourage a VI child to crawl and move around • Help the child begin to orient themselves using sound • Provide a fun and safe way for the child to play and exercise without excessive parental supervision
